A wireless lighting system used with demountable equipment, including truck-mounted forklifts (TMFL). The system includes a transmitter installed in a lighting harness or trailer lighting socket on a transporting vehicle. When the transporting vehicle's notification lights or signals (turn signals, tail lights, brake lights, clearance lights, reverse lights) are activated, a wireless signal is transmitted to a wireless receiver located on the TMFL, and a corresponding light or lights are activated on the TMFL. The system utilizes the power source of the TMFL to power the notification lights of the TMFL while being transported. Further, when the forklift is dismounted and in operation, the wireless lighting system is disabled until the forklift is returned to the transport position on the transport vehicle. This prevents actuation of the lights on the forklift unless the forklift is on the transport vehicle.

When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

A system for automatic controlling of sonic and visual warnings on a vehicle is provided. The system uses a controller and software configured to the task of initiating sonic and light emission warnings of vehicle movement to surrounding workers in the area of the vehicle. Signals from engaged light and sound sensors may be employed to alter the sonic warnings to a more easily heard frequency and the light emitted warnings to a more easily seen color and brightness.

A lighting tower system is provided. The lighting tower system includes a tower positioned in an upright orientation within a bed of a vehicle. The tower includes a base tube section and an upper tube section. The base and upper tube sections include a common longitudinal axis and are arranged to slide relative to one another in a telescoping relationship to move each tower between a retracted position and a fully extended position. The lighting tower system includes a light assembly coupled to and extending from the upper tube section of the tower. The light assembly is configured to rotate with respect to the common longitudinal axis and to tilt with respect to an axis perpendicular to the common longitudinal axis. The lighting tower system includes a mounting configuration configured to attach and detach the tower to the bed of the vehicle in the upright orientation.

Vehicle exterior lighting systems for vehicles equipped with tailgate assemblies may be configured to provide redundant backup lighting functionality for all tailgate positions (e.g., closed, open, and removed). Exemplary systems may include both vehicle static body structure mounted backup lamps and tailgate structure mounted backup lamps for providing the backup lighting redundancy.

A trailer lighting activation system includes a vehicle light sensor, an ambient light sensor, and a microcontroller. The vehicle light sensor is removably attached to a towing vehicle light to detect a light output of the towing vehicle light, and to provide a vehicle light sensor output signal in response to the light output of the towing vehicle light. The ambient light sensor can detect an ambient light level and provide an output signal in response to the ambient light level. The microcontroller is coupled to the vehicle light sensor output and to the ambient light sensor and has an output for energizing a trailer light in response to the ambient light sensor output signal and the vehicle light sensor output signal. An overcurrent monitor is coupled to the trailer light and to monitor current drawn by the trailer lighting activation system.
